GA'S FILTER.

Application filed September 4, 1924.

T 0 all whom it may concern.

Be it known that I, REGINALD M. RAN- YARD, a citizen of the United States, residing at Palms, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas Filters, of which the following is a specification.

This invention relates to in'iprm'ements in gas filters.

It is an object of the invention to provide a suitable filter adapted to be, readily inserted in a pipe line which will filter the gas passing therethrough and which is provided with a suitable bafile plate associated with the filter so that particles of solid ma terial and fluids may be separated out of the gas passing through the filter.

It is a further object of the invention to provide a gas filter which is simple and cheaply constructed and which has its parts so arranged that the filtering material may be easily and quickly withdrawn and replaced.

Vith the foregoing and other objects n view which will be made manifest in the following detailed description. reference 18 had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a vertical section through the improved gas filter,

Fig. 2 is a horizontal section taken substantially on the line 22 of Fig. 1, and

Fig. 3 is a vertical section taken substantially on the line 3-3 of Fig. 1.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout. the improved filter consists of a cylindrical shell 10 having an open top and about the upper edge of which is formed a suitable flange 11. A plate 12 is adapted to rest upon the flange 11 and to be secured thereto by means of bolts 13.

Upon one side of the shell 10 is formed a nipple 14 carrying a flange 17 adapted to be secured to the flange 16 of a pipe P by means of bolts 17. Gaskets 18 are preferably inserted betwecn the flanges 15 and 16. The nipple 14; which communicates with the interior of the shell 10 may be cast integral with the shell 10 or may be formed of a separate member and welded thereto.

taken Serial No. 735,887.

Upon the opposite side of the shell 10 is secured a hemispherical chamber 19 which communicates with the interior of the shell 10 and which may be secured by welding. The hemispherical chamber 19 is provided with an exhaust or discharge nipple 20 provided with a flange 21 adapted to be secured to the flange 22 of a pipe P by means of bolts 23. Suitable gaskets 24 may be inserted between the flanges 21 and 22. A plurality of arms 25 are secured interiorly of the hemispherical chamber 19 and extend across the discharge opening formed by the nipple 20.

A fibrous filtering material 26 is placed in the hemisphericalchamber 19 and is adapted to hold a screen 25 against the arms 25. A cylindrical receptacle 27 is adapted to be placed into the cylindrical shell 10 and is provided with an opening 28 adapted to register with the opening provided by the nipple 14. A larger opening 29 is formed in the receptacle 27 adapted to register with the opening provided in the shell 10 by the hemispherical chamber 19. A section of wire screen 30 is adapted to be placed between the receptacle 27 and the shell 10 upon that side of the shell 10 adjacent the hemispherical chamber 19 so that the screen 30 serves as a forward wall for enclosing the fibrous filtering material 26. A baffle plate 31 extends diametrically across the receptacle 27 and is welded thereto and extends downwardly from the top thereof to a point a short distance from the raised bottom 32 of the receptacle 27.

A suitable handhole 33 is formed in the bafile plate 31 to facilitate the withdrawal of the receptacle 27 from the shell 10 when it is desired to clean the filter and renew the fibrous filtering material 26.

The raised bottom 32 is provided with an aperture 32 extending therethrough which communicates with a chamber 34 formed between the bottom of the shell 10 and the bottom 32 of the receptacle 27. An opening is formed adjacent the bottom of the shell 10 and is interiorly threaded to receive a threaded plug 36. WVater or other fluid which is separated from the gas flowing through the filter may pass through the aperture 32 into the chamber 34 and to be withdrawn therefrom upon removal of the plug 36, a suitable openin 37 having been formed in the receptacle 2? to register with the opening 35 in the shell 10.

\Vhen the filter is inserted into a gas line gas enters the filter through the pipe P. striking the battle plate 31. Upon striking the battle plate 31. water and particles of solid material are stopped and tend to fall to the bottom of the sleeve 27. the passing downwardly and around the bottom of the plate 31 through the screen 30. the fibrous filtering material 26. and the screen 25, and is discharged through the pipe P. A small quantity of gas passes through the battle plate 31 by means of the handhole 33. By providing the separate chamber irl from the chamber above the bottom 32. the water separated from the will be kept out of contact with succeeding gas passing through the filter.

\Vhen it is desired to clean the filter. it ,merely necessary to remove the bolts 13 and the plate 12 and to withdraw the complete receptacle 27. This will lift out any par ticles of solid material which have collected upon the bottom 32. The screen 30 may then be removed and the fibrous filtering material 26 can be withdrawn from the hemispherical chamber 19 and be replaced.

It is to be understood that various changes may be made in the detail of construction without departing from the spirit or scope of the invention as defined by the appended claims.
